  • Jamaica-Nicaragua Bridge Structure

    Jamaica-Nicaragua Bridge Structure

    Edward Long describes it in his History of Jamaica printed in 1774: This bridge is flat and composed of planks on frame of timberwork which rests upon two piers and two buttresses projecting from the banks, constructed with piles and braces interlaced with masonry. The Flat Bridge is a beam bridge across the Rio Cobre on the A1 road connecting the Jamaican capital Kingston, with the north coast tourist areas of Dunn's River and Ocho Rios. It is one of the oldest bridges in Jamaica. Get ready for a deep dive that'll change the way you see. The documentation Centre was launched on July 2, 2001 to support the NWA with the strategic objective to be the primary source of formation on road infrastructure and associate works and services. The Centre is located on the ground floor of the Agency's Corporate Office and serves both staff and. Ever wondered about the bridges of Jamaica? They're more than just pathways; they're essential lifelines that connect communities, boost the economy, and tell a story of engineering and resilience. The bridge's simple yet enduring timber and masonry structure dates back to the 18th century, making it one of Jamaica's oldest river.
